I actually loved the ending to the Dark Tower series. I also loved all the books, and The Waste Lands was my favourite. Each their own I guess.
Can't reccomend A Game of Thrones enough. Except for the fact he's taking AGES to release the next book
Currently on book 3 of 'The Earthsea Quartet'. Loved the first book, 2nd grew on me as I read it and I'm really enjoying the 3rd so far as well.
